Thirty-yearling Menz lambs with average initial body weight of 19.72 ± 1.96 kg (Mean ± SD) were used to evaluate the effects of supplementing mung bean haulms (MBH) and concentrate mixture (CM) on feed intake, body weight gain and carcass characteristics of lambs fed a basal diet of natural pasture hay. The lambs were assigned into five treatments in a randomized complete block design as follows: 226 CM (T1), 77 MBH + 192 CM (T2), 154 MBH + 156 CM (T3), 231 MBH + 120 CM (T4), 308 MBH + 87 CM (T5) grams on dry matter basis. Total dry matter (DM), organic matter and metabolizable energy intakes were increased (p 0.05) among treatments. Feed conversion efficiency for T2 was higher (p

ABSTRACTThe effects of various treatment options on the nutritional value of wheat straw as well as the growth performance of crossbred calves fed the treated wheat straw were evaluated. Twenty-four female calves (75% Friesian-Borana), weighing 99.3 ± 19.7 kg (aged 6–9 months), were divided into four groups of six animals using a randomized complete block design. The feeding trial lasted approximately 104 days. The dietary treatments were: untreated wheat straw (control T1), wheat straw treated with urea-molasses (T2), urea-lime (T3), and effective microorganisms (T4). Results showed that the treatment options affected the physical silage quality and chemical composition of wheat straw. Calves in the T3 and T4 groups had a higher daily DM intake (3.7 and 3.5 kg/head, respectively) than those in T2 (3.1 kg/head) and T1 (3.02 kg/head) groups. Calves in the T3 (422.7 g/d) and T4 (391 g/d) groups gained greater weight than those in the T2 (281.7 g/d) and T1 (204.4 g/d) groups (P

The study was conducted to evaluate the yield performance of improved forage and food crops and to estimate the profitability of fodder and food crops in Holetta and Ejere areas, central highlands of Ethiopia during 2019 and 2020 cropping seasons. The experiment was laid out in randomized complete block design with three replications and evaluated two annual forage crops, two perennial forage crops, and two cereal food crops. Data on herbage dry matter (DM) yield was collected for forage crops while straw and grain yields were measured for food crops. Partial budget analysis was made to evaluate the economic feasibility of forage and food crops production. The result revealed that the herbage DM yield varied (P

IntroductionMaralfalfa grass (Pennisetum spp.) is known for its high dry matter productivity and nutritive value. However, information on agronomic management practices to improve yield and nutritive value in Ethiopia is sparse.Materials and methodThe experiment consisted of 7 plant densities (33,333 [75 cm × 40 cm]; 26,667[75 cm × 50 cm]; 25,000 [100 cm × 40 cm]; 22,222 [75 cm × 60 cm]; 20,000 [100 cm × 50 cm]; 16,667 [100 cm × 60 cm]; and 13,333 [125 cm × 60 cm] plants per hectare, and arranged in randomized complete block design with three replications.ResultsThe results indicated that the year had a significant (P0.05) effect on the number of nodes and leaves per plant, leaf length, and basal diameters. The number of tillers per plant varied significantly among plant densities only in the first year at the 1st harvest. Plant height in the first year was significantly (P 0.05) influenced by plant density. Using a lower plant density could reduce the amount of planting material, transport, and labor costs.ConclusionHowever, further studies on Maralfalfa grass should be conducted in multi-locations of Ethiopia both under rain-fed and irrigated conditions with various agronomic practices.

Dairy cattle production is an integral part of smallholder farming systems in the central highlands of Ethiopia, but it is characterized by low milk productivity mainly due to nutritional constraints. This study assessed the comparative advantage of using improved forage-based feeding system over the traditional feeding practices on feed intake, milk yield and quality, and cost benefit analysis of crossbred dairy cows under smallholder farmers. The study was conducted at Welmera and Ejere districts on 12 farmers and two cows per farmer, and two dietary treatments were assigned to each cow randomly, and the study lasted 8 weeks. The treatments were: 1) intervention diet composed of oats-vetch mixture hay with concentrate supplementation at the rate of 0.5 kg/l of milk and 2) basal diet following farmers’ current feeding practices: crop residues and native hay, commonly soaked with local brewery residue (“Atela”) and water. The results showed that there was no difference in total dry matter intake between the two diets. However, the basal feed intake was higher in the traditional feeding practice by 11% whereas the concentrate intake was higher in the intervention diet by 25%. Crude protein intake was significantly higher (P
